Disassemblies

From Sonic Retro

This pages lists all the public disassemblies made by the Sonic hacking community. Some of these disassemblies are still being worked on on the GitHub account, which are more up-to-date and accurate than those listed on this page, and are already split.

Sonic 1 (Updated AS Disassembly by Shadow05)(info) (2.74 MB) - A vastly improved version of Hivebrain's AS disassembly. It's better labeled than the original version and includes more features, it's SonLVL compatible, and project files are bundled.

Sonic 1 (Split and Text by Hivebrain) (ASM68K)(info) (1,016 kB) - A modified version of Hivebrain's split disassembly targeting ASM68K. As a result, it builds much faster, does not need to use an external program for includes (and hence bypasses s1comb.asm), and can be optimized in various ways. The GitHub version of the Sonic 1 disassembly is based on this version.

Sonic 1 (Split and Text by Hivebrain) (AS)(info) (1,008 kB) - A modified version of Hivebrain's split disassembly targeting AS. As a result, it does not need to use an external program for includes (and hence bypasses s1comb.asm), and AS-specific features such as functions, nameless temporary labels and improved macro facilities can be used. Tools for building for Linux are available here(info) (1.51 MB) and Mac users should click here(info) (1.4 MB) for build tools.

Sonic 1 (Split and Text by Hivebrain)(info) (771 kB) - The June 2005 release of Hivebrain's Sonic 1 split disassembly. SonED2 project files are available here. It targets SNASM68k. Very well labeled, but because of certain problems with SNASM68k it is recommended to use either the ASM68k version or the AS version of this disassembly (also note that this version doesn't work with any 64 bit OS and may not work with Windows 2000/XP/Vista/7!) .

Sonic 2 Nick Arcade prototype

Sonic 2 Early Prototype (Text Format by drx) - A disassembly of the Sonic the Hedgehog 2 Nick Arcade Prototype, by drx. This is in text format and can be opened in any editor. It targets SNASM68k (also note that this version doesn't work with any 64 bit OS and may not work with Windows 2000/XP/Vista/7!).

Revision 01

Sonic 2 (Split and Text by Xenowhirl) - The 2007 release of the disassembly of Sonic the Hedgehog 2, by Xenowhirl. It is far better labeled than its predecessors and the assembly times are very fast (1-5 seconds). The disassembly itself is fully SonED2 compatible, and project files are bundled. It targets the Macro Assembler AS, and is cross-platform. The GitHub version of the Sonic 2 disassembly is based on this version. Tools for building for Linux are available here and Mac users should click here for build tools. Very highly recommended.

Sonic 2 (Split Format by Nemesis) - Nemesis's Sonic 2 split disassembly, targeting SNASM68k. This disassembly is rather slow to rebuild due to the use of an external program (combine.exe) to insert binary files into the ROM - the following two disassemblies work around this by using incbins instead of combine.exe:

Sonic 2 (Text Format with Incbin by shobiz) - A drop-in replacement for the s2.asm file in Nemesis' Sonic 2 split disassembly, by shobiz. This disassembly uses incbins to greatly speed up compile times. It is also fully SonED2 compatible without requiring any modifications. This disassembly targets SNASM68k and works on Windows 2000/XP.

Sonic 2 (Text Format with Incbin by Xenowhirl) - Identical to shobiz's modified disassembly, but works on Windows 95/98/ME/NT as well as DOSBox. It does not work on Windows 2000 or XP due to a difference in the way these operating systems handle 8.3 short filenames.

Sonic 2 (Split and Text by Aurochs) - The 2006 release of the disassembly of Sonic the Hedgehog 2, by Aurochs. It is better labeled than Nemesis' disassembly and the compile times are much faster. The disassembly itself is fully SonED2 compatible, and project files are bundled. It targets the Macro Assembler AS, and is cross-platform.

Revision 02

The GitHub version of Revision 01 allows for a complete building of revision 02.

released his disassembly of the version of Sonic 2 from Sonic Classics a.k.a. Sonic Compilation, which has come to be thought of as ‘revision 2’/‘REV02’ and includes several bug-fixes and other changes when compared to earlier versions. The release followed a lengthy discussion on how to enhance Sonic 2 with bug-fixes and other changes, several of which were noted by Esrael as having already been fixed in this relatively little-known revision, which he had become experienced with via using it as the code-base for recent versions of his hack Sonic 2 Delta. Esrael had already released the unaltered ROM of this version earlier in the thread.

Sonic & Knuckles

Sonic & Knuckles (Split Format by jman2050) A split disassembly of Sonic & Knuckles created by jman2050 and a variety of other contributors, using Stealth's disassembly. The GitHub version is based on this disassembly.
